IMPROVEMENT IN ATTACHING KNOBS TO ROSES.

Specification forming part of Letters Patent No. 133,889, dated December 10, 1872.

To all whom it may concern:

vBe it known that I, CHRISTOPHER F. REB= STOCK, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Door-Knobs; and I do hereby declare the following, when taken in connection With the accompanying drawing, and the lettersv of re'ference narked thereon,

to be a full, clear, and exact description of the invention consists in the peculiar manner hereafterdescribed for connecting the rose directly to the neck of the knob, so that when the rose is secured to the door it also secures the knob in position without direct attachment to the spindle.

The knob A is formed from sheet metal, of any desirable form, by spinning or striking up.

The neck B is a tube of sheet metal attached to or made a part of the knob, and in order to form a seat within the neck of the spindle lIfill the neck with any suitable fusible matet rial a, iirst placing therein a core of the form and size of the spindle, and so soon as the metal poured therein has cooled and attached itself to the sleeve I remove the core, and the neck is complete. As a means for securing the knob in place upon the door I form a bead, b, around the neck, and construct the rose B with an inwardly-projecting tlange,.c, which will pass on over the end of the neck and rest upon the bead b, as seen in Fig. 1. The edge of the neck projecting beyond the filling is, by spinning or otherwise, turned down on the ange c', as seen in Fig. 1, thus securing the two parts firmly together; then, when the knob y. is placed upon the door, screws are inserted through the rose in the usual manner, and these hold the knob in' position, the connection being, between the knob and the rose, and such as to allow the knob to turn freely.

I claim as my invention- A knob having a sheet-metal neck construct ed with a bead, b, combined with a rose, d,

resting upon the said bead, and secured together by turning the metal of the neck down upon the rose., substantially as set forth.

CHRISTOPHER F. REBSTOCK.
